What is Foreign Exchange Risk?

Foreign exchange risk (also called currency risk) is the possibility that exchange rates will move unfavorably, reducing your investment returns when converting foreign currency back to your home currency. Every international investor faces this risk automatically.

Short answer

Foreign exchange risk is the danger that currency exchange rates will change unfavorably, lowering your returns when converting foreign currency to your home currency. It affects all international investments.

Step-by-step worked examples

US investor buys €10,000 of German bonds at €1 = $1.10. Six months later EUR drops to €1 = $0.95. What is the FX loss?

Initial investment = €10,000 × 1.10 = $11,000
Current value = €10,000 × 0.95 = $9,500
FX loss = $11,000 − $9,500 = $1,500 (even if bonds gained interest)

Japanese investor buys $100,000 US stock at ¥100/$1. Dollar weakens to ¥80/$1. Yen loss on conversion?

Initial: $100,000 = ¥10,000,000
Later: $100,000 = ¥8,000,000
Loss = ¥2,000,000 even if stock gained value

Australian investor buys Indian Rupee bonds yielding 7% annual return. INR depreciates 8% in one year. Net return?

Bond return = +7%
Currency depreciation = −8%
Net return = +7% − 8% = −1% loss
